Nitrous Wet System Fuel Pressure / Jet Map Reference Table

EFI WET SYSTEM JET MAPIf you are building a custom direct port nitrous system or retrofitting a wet system to an application other than what it was specifically designed for please refer to the following table for a ballpark jetting and fuel pressure combination. Edelbrock nitrous systems come with jetting calibrations determined thru dyno testing for specific engine displacement and configurations. Beside displacement and aftermarket engine performance parts there are numerous variables that effect tuning for a specific application. For further information regarding nitrous tuning please refer to the Nitrous Support section.
